- 1. 2/2 To order numbers Level 2 PROMPT sheet Numbers can be ordered by looking at the value of each digit Example: 2/1 To count by grouping To order 83 3 87 8 80 78 Tens Units Example1: Here are 20 sweets to share TU Each child gets 5 sweets 83 How many children are there? 03 Divide them up into groups of 5 sweets-like this 87 08 80 78 The order would be; 3 8 78 80 83 87 smallest largest 2/3 Numbers sequences There must be 4 children Look to see what you already know Example1: 1 4 7 10 ..... ..... Example2: Here are 12 marbles to share +3 +3 +3 There are 4 children. The numbers are going up- ascending How many marbles does each get? They go up by 3 each time Continue with this rule Divide them up into 4 groups - like this 1 4 7 10 13 16 +3 +3 Example1: 13 11 9 7 ..... ..... -2 -2 -2 The numbers are going down - descending They go down by 2 each time Continue with this rule-count backwards 13 11 9 7 5 3 -2 -2 Each child gets 3 marbles

How many legs do they have altogether? 5+5 Addition sentence Multiplication sentence 2+2+2=6 3x2=6 These are so good to learn – believe me Repeated addition is the same as multiplication Addition sentence Multiplication sentence 5 + 5 + 5 + 5 = 20 4 x 5 = 20 10 + 10 + 10 = 30 3 x 10 = 30
- 4. 2/10 Repeated subtraction (Division) 2/12 Record work as a number sentence Repeated subtraction is the same as division Example 1 15 There are 12 people on a bus. This is the same as At the next stop 4 people get off and 7 get on -5 (1) 15 ÷ 5 = 3 How many are on the bus now? 10 -5 (2) Number sentence Because 5 has been 12 – 4 + 7 = 15 5 subtracted 3 times -5 (3) to get to 0 Example 2 0 Pavan’s cat weighs 18kg. Olivia’s dog weighs 32kg. How much heavier is Olivia’s dog? Number sentence 2/11 Solve number problems 32 – 18 = 14 The order can be changed Example 3 Example: Sana had 50p. She spent 24p. How much did she 13 + 6 + 7 = 13 + 7 + 6 = 20 + 6 = 26 have left? Number sentence 50 - 24 = 26p The number can be partitioned Example: Example 4 10 + 15 = 10 + 10 + 5 = 20 + 5 = 25 Aabid has 20p and Claudia has 41p. How much do they have altogether? Number sentence A partial number line can be used Example: 20 + 41 = 61p 37 + 8 = 45 +8 +3 +5 2/13 Names of 2D shapes 37 40 45 22 – 3 = 19 -1 -2 Triangle Square Pentagon 19 20 22 Hexagon Circle Octagon
